An external AC to direct current (DC) converter 42 may be included to convert the AC power to DC power, so that the power transmitter 38 then converts the DC power into the wireless power.

One or more additional sources 14 (or portions thereof) may be included in the system 10. The sources 14 may be electrically connected to each other in any suitable manner to achieve a desired result. The sources 14 may be electrically connected in series or in parallel.

For example, one or more power transmitters 38, each with an associated point of emission 16, may be included. FIG. 2 illustrates a plurality of power transmitters 38 connected in series, where each power transmitter 38 is connected to a point of emission 16. FIG. 3 illustrates a plurality of power transmitters 38 connected in parallel, where each power transmitter 38 is connected to a point of emission 16.

Likewise, for example, FIG. 4 illustrates one power transmitter 38 connected to a plurality of points of emission, where the points of emission are connected in series. FIG. 5 illustrates one power transmitter 38 connected to a plurality of points of emission, where the points of emission are connected in parallel.

The types of energy used with the point of emission 16 include, but are not limited to, RF (electromagnetic field), inductive (magnetic field), capacitive (electric field), visible light, infrared (IR) light, ultra-violet (UV) light, solar, subsonic, sonic, ultrasonic, vibration, wind, pressure (short and long wavelength), or any other type of energy. As such, a point of emission 16 may include an antenna 62, a coil, a plate, a light bulb, an LED 54, a laser, a diode, an IR detector, a UV bulb, a full spectrum light bulb, a speaker, a piezoelectric element 32, a vibrating element 32, a fan, and/or the like.

Referring to FIG. 1, the target 18 preferably includes a power receiver 40 connected to a point of reception 20 (POR). The point of reception 20 receives the emitted (wireless) power (from the point(s) of emission) and supplies the wireless power to the power receiver 40. The power receiver 40 converts the wireless power into a useable power (form) that is utilizable by the component 22. For example, the component 22 may require AC or DC power, or a combination of the two, for activation.

The power receiver 40 and the point of reception 20 may be of any design that accomplishes the objectives of the invention (i.e., receiving emitted power/energy from a source 14). The power receiver 40 and the point of reception 20 may be connected through any suitable means.

The power receiver 40 preferably includes a power harvester for converting wireless power to DC power.

The point of reception 20 may be incorporated into the item 12 itself. For example, the point of reception 20 may be inside the item 12, part of the item 12, or outside the item 12. The point of reception 20 may be incorporated into the mechanism for hanging, mounting, or otherwise displaying the item 12. For example, a loop for hanging the item 12 may be a portion of or the entire point of reception 20, as shown in FIG. 18 where the loop for hanging is also an antenna 62 (point of reception 20) connected to the power receiver 40.

One or more additional targets 18 (or portions thereof) may be included in the system 10. The targets 18 may be electrically connected to each other in any suitable manner to achieve a desired result. The targets 18 may be electrically connected in series or in parallel.

For example, one or more power receivers 40, each with an associated point of reception 20, may be included. FIG. 6 illustrates a plurality of power receivers 40 connected in series, where each power receiver 40 is connected to a point of reception 20. FIG. 7 illustrates a plurality of power receivers 40 connected in parallel, where each power receiver 40 is connected to a point of reception 20. In either case, the advantage is more uniform power distribution to the multiple components 22. As an example, one power receiver 40 may be oriented improperly or located in a location with no or low wireless power density. The result may be a reduced power output for that receiver 40. The other power receivers 40, however, may be receiving sufficient power and may supply some of that power to any other receiver 40 receiving less power.

Likewise, for example, FIG. 8 illustrates one power receiver 40 connected to a plurality of points of reception, where the points of reception are connected in parallel. FIG. 9 illustrates one power receiver 40 connected to a plurality of points of reception, where the points of reception are connected in series. In either case, the advantages are increased power reception and increased probability of receiving sufficient power. As an example, one point of reception 20 may be oriented improperly or located in a location with no or low wireless power density. The result may be a reduced power output for that point of reception 20. The other points of reception, however, may be receiving sufficient power which is supplied to the power receiver 40. It should be noted that the multiple points of reception shown in any of the figures may be directly connected together or combined using a combiner or other combining device.

The types of energy used with the point of reception 20 include, but are not limited to, RF (electromagnetic field), inductive (magnetic field), capacitive (electric field), visible light, infrared (IR) light, ultra-violet (UV) light, solar, subsonic, sonic, ultrasonic, vibration, wind, pressure (short and long wavelength), or any other type of energy.

FIG. 7 illustrates a plurality of components 22 connected to a plurality of power receivers 40, where the power receivers 40 are connected in parallel.

Referring to FIG. 18, the component 22 and the target 18 may be incorporated into the item 12. The item 12 may be an ornament 28 for a holiday tree (e.g., a lighted Christmas tree). The item 12 may also be a window decoration (e.g., a lighted snowflake). One or more items 12 may be configured to work together to achieve a desired outcome (e.g., a light or sound sequence). One or more items 12 may be electrically connected to each other to achieve the desired outcome.

The system 10 may be configured to pulse power. Pulsing may be used to turn on and off any point of emission 16 as desired. For example, each point of emission 16 of the system 10 may be turned on then off sequentially. The points of emission may turn on or off in a sequence that produces desired changes in the amount of power wirelessly supplied to the point of reception 20 and/or component 22. As an example, the points of emission may be used to wirelessly power lights on a Christmas tree. The points of emission may turn on and off in order to make different lights at different locations turn on and off to produce blinking and other stimulating light sequences. Pulsing of the points of emission may also be used to increase the range of the wireless power and/or efficiency of the conversion of wireless energy to a useable form. Pulsing methods are described in U.S. patent application Ser. No. 11/356,892 and U.S. Provisional Patent Application No. 60/758,018, both entitled Pulsing Transmission Method and incorporated herein by reference. Pulsing networks are described in U.S. patent application Ser. No. 11/356,892 and U.S. Provisional Patent Application No. 60/758,018, both entitled Pulsing Transmission Network and incorporated herein by reference.

Referring to FIG. 19, a controller 64 may be incorporated into the system 10 to control a source 14, a target 18, a component 22, and/or an item 12 to achieve a desired outcome. One or more additional controllers 64 may be included. The one or more controllers 64 may be connected to one or more of the sources 14, targets 18, components 22, items 12, and/or each other. The controller 64 may be, but is not limited to, a microprocessor.

For example, a controller 64 may be used to pulse power by turning specific points of emission on and off. For another example, a controller 64 may be used to direct power to a particular target 18 via a particular source 14. The switch 50 may be, but is not limited to, a SPST or SPDT relay, pin diode switch 50, or a transistor such as a PMOS.

Referring to FIG. 20, a switch 50 may be incorporated into the system 10 to achieve a desired outcome. One or more additional switches 50 may be included. The one or more switches 50 may be connected to one or more of the sources 14, targets 18, components 22, items 12, controllers 64, and/or each other.

For example, a switch 50 may be used to pulse power by accepting and passing power at specific points of emission. For another example, a switch 50 may be used to accept or pass power to a particular target 18 via a particular source 14. For another example, as illustrated in FIG. 20, a plurality of switches 50 may be used to turn components 22 on and off.

In the present invention, the system 10 may be made up of any embodiment source 14, any embodiment target 18, and any embodiment component 22. Each of the source 14, target 18, and component 22 (of multiples of each) may be configured to perform individually or collaboratively. Thus, the system 10 is flexible so that a wide variety of desired outcomes are achievable.

Thus, for a holiday light application, the system 10 can be designed to have the lights on constantly, to turn individual lights on and off to create various patterns (blinking, sequences), to dim the lights, to change colors with different colored bulbs or LEDs 54. For a sound application, the system 10 can be designed to play various tunes by turning on and off the musical elements 32 in the appropriate order and for the appropriate duration.

The system 10 may be configured to recirculate excess or unused power. Heat generated by the system 10 may be captured and used by other sub-assemblies of the system 10. For example, to heat a potpourri sub-assembly 24 or to heat water in a base 30 of a Christmas tree (for potpourri). As another example, the heat may be harvested and turned into electrical energy which may be supplied back to the system 10.

It should be noted that various other electrical components 22 may be added as required by the system 10 or as desired. As an example, a series resistor may be added to the component 22 (e.g., LED 54) in order to limit current.

For example, referring to FIG. 21, a system 10 according to the present invention for wirelessly powering a plurality of items 12 is illustrated. The system 10 includes a source 14, a plurality of targets 18, and a plurality of components 22.

In this example, each of the plurality of items 12 is an illuminating snowflake. Each of the plurality of items 12 includes a target 18, a component 22, and a mechanism for hanging the item 12.

The source 14 is connected to a plug that engages an AC outlet. AC power is supplied via the plug to an AC to DC converter 42. The AC to DC converter 42 converts the AC power to DC power and supplies the DC power to a power transmitter 38. The power transmitter 38 converts the DC power to wireless power and supplies the wireless power to a plurality of points of emission via a plurality of switches 50. The controller 64 and the switches 50 direct the flow of power to the points of emission. The points of emission transmit the wireless power over a distance to the targets 18.

Each target 18 includes a point of reception 20 and a power receiver 40. Each point of reception 20 receives the wireless power sent by one or more points of emission. Each point of reception 20 supplies the wireless power to the power receiver 40 connected thereto. The power receiver 40 converts the wireless power to DC power and supplies the DC power to the component 22.

In this example, each component 22 is an LED 54 for illuminating its associated snowflake. Each LED 54 receives DC power from the power receiver 40 and is activated or turned on.

Thus, in this example system 10, a single source 14 is utilized to send power wirelessly to a series of snowflakes, causing the snowflakes to light up. The controller 64 may be configured to vary the intensities or colors of the LEDs 54, vary the durations that the LEDs 54 are lit up, vary the sequence of LED 54 lighting among the group of snowflakes, etc. As an example, each snowflake may have a timing circuit or microprocessor that cycles through a sequence of different colors, intensities, and/or durations. The sequence may be predetermined or random. The timer may be synchronized by a pulsing waveform from the power transmitter(s) 38. As an example, the power transmitter(s) 38 may pulse for ten seconds. This ten-second period may be followed by a 1 second off period in order to reset the timers in the power receivers 40. The snowflakes may function from stored energy during this off period or may turn off with the power transmitter 38.

FIG. 22 shows another example of a snowflake suitable to be incorporated in the system 10 illustrated in FIG. 21. This snowflake includes a target 18 having a single power receiver 40, a point of reception 20, and multiple components 22 (LEDs 54).

Referring to FIGS. 23-24, an assembly 24, according to the present invention, includes a system 10 for wirelessly powering an item 12 and a structure 26 for supporting at least a portion of the system 10.

The system 10 is any system 10 according to the present invention. The system 10 includes at least one source 14, at least one target 18, and at least one component 22. The structure 26 is any structure 26 capable of physically supporting any part or all of the system 10.

In the example illustrated in FIG. 23, the structure 26 is a Christmas tree. The system 10 includes a single source 14, a single target 18, and a single component 22. The target 18 and the component 22 are incorporated into the item 12 to be powered. For example, the item 12 may be an illuminating ornament 28, where the component 22 is an LED 54, or a musical ornament 28, where the component 22 is a music maker, such as a single recording of an MP3 player. The item 12 includes a loop for hanging the ornament 28 on the Christmas tree.

In the example illustrated in FIG. 24, the structure 26 is a Christmas tree. The system 10 includes a plurality of sources 14, a plurality of targets 18, and a plurality of components 22. One target 18 and one component 22 are incorporated into one item 12 to be powered. For example, the items 12 may be illuminating ornaments 28, where the components 22 are LEDs 54, or musical ornaments 28, where the components 22 are music makers. The items 12 include a loop for hanging the ornaments 28 on the Christmas tree.

It should be noted that this embodiment may be used with a real or artificial tree. The source 14 may be built into the tree or be an add-on product. The tree may have lights or strings of lights. There is, preferably, a string of lights (as an example, 4 LEDs 54) dedicated to each branch where the string of lights is wirelessly powered.

FIGS. 25-29 illustrate various possible variations of embodiments of the present invention (these examples are not meant to be limiting).

A remote control may be included to control operation of the system 10. For example, to turn the system 10 on and off, to vary the intensity or brightness of lights/LEDs 54. A timer or sensor 52 (e.g., light detector) may be included to control operation of the system 10.

For any item 12 or source 14, a face (or body) of the item 12 or source 14 may be interchangeable with a second face for the item 12 or source 14. For example, if the item 12 is a snowflake, the face defining the snowflake may be removed and replaced with a jack-o-lantern, such that the item 12 may be used for multiple occasions. As a specific example, the item 12 may be designed to accept the target 18 (the point of reception 20 and the power receiver 40) that is formed as a rectangular unit that snaps into the face that defines the shape of the item 12. The resulting target 18 can then be removed from one item 12 by releasing securing snaps 66 and snapping the target 18 into a target holder 68 of the other item 12. An example of this can be seen in FIG. 29 where the faces or items 12 are a star and a tree.

Similarly, a target 18 may be interchangeable between various components 22 and/or items 12. This allows the target 18 to be used with a multitude of different components 22/items 12.

The system 10 may include a communication component in order to send data between parts of the system 10.

It should be noted that wireless power in any polarization, sense of rotation, magnitude, wavelength, or any other characteristic may be used in any of the embodiments to make the system 10, apparatus, or assembly 24 more robust in operation (work in any orientation, polarization, or position).

In any embodiment of the present invention, the power transmitted may be limited to include power only, that is, data is not present in the signal. If data is required by the application, the data is, preferably, transmitted separately and/or has a separate receiver 40, for example, via the communication component discussed above.

FIG. 30 illustrates where a portion of the POR 20 is used for mounting. The POR, in this case a dipole antenna, consists of a piece of wire 70 to make up half of the antenna 62, and a rigid section 72 to make up the second half of the antenna 62. The wire 70 may be cut to length to tune the antenna to 50 ohms. The POR is then hung on a structure 26 such as a branch or dowel. The weight of the receiver 40 and component 22 and rigid section 72 of antenna 62 then adds tension to the wire 70 allowing it to achieve the appropriate length for appropriate tuning, and alignment to the POE (not shown).

FIG. 31 illustrates where the entire POR 20 is used for mounting. The POR 20—in this case may be a monopole, loop, or other type of single element antenna 62—consists of a piece of wire 70 to make up the entire antenna 62. The wire 70 may be cut to length to tune the antenna 62 to 50 ohms. The POR is then hung on a structure 26 such as a branch or dowel. The weight of the receiver 40 and component 22 may add tension to the wire 70 allowing it to achieve the appropriate length for appropriate tuning, and alignment to the POE (not shown).

FIG. 30 illustrates where a portion of the POR 20 is used for mounting. The POR 20, in this case a dipole antenna 62, consists of a piece of wire 70 to make up half of the antenna 62, and a rigid section 72 to make up the second half of the antenna 62, which may be wire 70, a printed circuit board, or other conductive element. The wire 70 may be cut to length to tune the antenna 62 to 50 ohms, and the gauge of the wire 70 may be selected so that it is strong enough to support the weight of the ornament 28. The POR 20 is then hung on a structure 26 such as a branch or dowel. The weight of the receiver 40 and component 22 and rigid section 72 of antenna 62 then add tension to the wire 70 allowing it to maintain the appropriate length for appropriate tuning, and alignment to the POE (not shown).

As an example in FIG. 32, a dipole antenna 62 is used as the POR 20. As RF energy is received at the POR 20, it is converted to DC power by the receiver 40 and used by an LED 54 to light the ornament 28. The top half of the dipole antenna 62 is a 30 AWG stranded wire with green insulation that forms a folded loop. This wire is used because it is strong enough to support the ornament 28, yet thin enough to be discrete and look like string or an ornament hook. The rigid section of the dipole antenna 62 is also 30 AWG stranded wire 70, though white insulation is used to make the wire 70 less visible. To tune the dipole both the length of the folded loop and the rigid wire 70 must be one quarter of the wavelength of the desired frequency of operation. For the example shown in FIG. 32, the frequency of operation is 915 MHz. One quarter of a 915 MHz wavelength is 81.910 mm. To tune the loop of the dipole, an appropriate length of wire is used so that when the ornament 28 is being supported by the wire as it is hung on the branch the quarter wavelength distance is measured from the connection point on the receiver 40 to the horizontal tangent of the loop. If a different material is used for the rigid section of the antenna 62 the dielectric will need to be taken into account when selecting the length of the conductive portion.

FIG. 31 illustrates where the entire POR 20 is used for mounting. The POR 20—in this case, may be a monopole, loop, or other type of single element antenna 62—consists of a piece of wire 70 to make up the entire antenna 62. The wire 70 may be cut to length to tune the antenna 62 to 50 ohms. The POR 20 is then hung on a structure 26, such as a branch or dowel. The weight of the receiver 40 and component 22 and may add tension to the wire 70 allowing it to achieve the appropriate length for appropriate tuning, and alignment to the POE (not shown).

As an example in FIG. 33, a monopole antenna 62 is used as the POR 20. As RF energy is received at the POR, it is converted to DC power by the receiver 40 and used by an LED 54 to light the ornament 28. The monopole antenna is a 30 AWG stranded wire 70 with green insulation. This wire 70 is used because it is strong enough to support the ornament 28, yet thin enough to be discrete and look like string or an ornament hook. The ground plane 74 for the monopole and the receiver 40 are a single item, though they are shown separately in FIG. 33 for clarity. To tune the monopole the length of the wire 70 formed was a folded loop must be one quarter of the wavelength of the desired frequency of operation. For the example shown in FIG. 33, the frequency of operation is 915 MHz. One quarter of a 915 MHz wavelength is 81.910 mm. To tune the monopole, an appropriate length of wire 70 is used so that when the ornament 28 is being supported by the wire 70 as it is hung on the branch the quarter wavelength distance is measured from the connection point on the receiver 40 to the horizontal tangent of the wire loop.

It will be understood by those skilled in the art that while the foregoing description sets forth in detail preferred embodiments of the present invention, modifications, additions, and changes might be made thereto without departing from the spirit and scope of the invention.
